Mystery spunker

Whilst on an 8 hour stopover in Bangkok airport I decided to have a tug to elevate boredom. I opted for the disabled toilet for more legroom. When I’d done I flushed the toilet to pretend I’d been in there actually pooing. On my exit there was a man on two crutches giving me evil eye so I did what anyone would do and put on a limp and hobbled away.
